Description

This change addresses an issue reported while testing Sumac, where the API V2 is on by default in the authoring MFE: openedx/wg-build-test-release#428. It fails when retrieving an empty list of courses with the queryparams api/contentstore/v2/home/courses?page=1&order=display_name. When this was implemented, the course authoring MFE rendered the empty lists only with page=1 query param (didn't do any filtering/ordering by default), which was later changed to page=1&order=display_name which now ordered by default.

This issue occurs because all the filtering and ordering are done under the assumption that course_overviews is always a query set. However, that's only true when there are courses available and CourseOverview.get_all_courses is used. When not, an empty list is returned instead, raising a 500 error in Studio.
